Question

2. Ravi applied a force of
3. Write the formula for speed and velocity.
What is law of conservation of energy?​

Answer 1

Answer:

The formula for speed is change in distance divided by change in time. The formula for velocity is change in displacement divided by change in time.

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.

Answer 2

Answer:

2. incomplete question

3. speed- distance travelled/time taken

velocity-displacement/time taken

Explanation:

4. It states that energy can neither be created nor destroyed, but it can be transformed from one form to another.

The total energy before and after the transformation remains the same.
